ROBERT H. HASSLER, or INDIANAPOLIS, INDIANA.

VOLUTE-SPRING-EQUIPPED RADIUS-ROD,

Application filed June 8, 1915.

7 '0 all whom it may (cavern:

Be it known that I, ROBERT H. HAssLER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in volute-Spring- Equipped Radius-R-ods, of which the following is a specification' The object of this invention is to connect the radius rods of motor-vehicles to'the frame and springs one of which is placed at each place of attachment of the rods to said frame and axles whereby the stress delivered longitudinally of the rod will be delivered radially of the volutes causing the resistance of their convolutions to act cumulatively in opposition.

The object also is to yieldingly resist torsonial and lateral stresses delivered through the rod.

Another object is to accomplish the above functions with mechanism that is free from frictional parts. Frictional or sliding parts after prolonged usage become loose and rattle. In my present invention the advantages of longitudinal and torsional resiliency are secured and at the same time the disadvantages of any sliding parts are avoided.

I accomplish the above and other objects which .will hereinafter appear by the mechanism illustrated in the accompanying drawings, in which- Figure .1 is a side elevation of an end of a front automobile axle with my invention applied in vertical section and showing some of the volute convolutions compressed. Fig. 2 is a top plan view of same. Fig 3 is a section on the line 3 3 of Fig. 1 showing the spring-casing broken awayin part, and Fig. 4 shows the application of my invention to the frame of the machine, the latter being in vertical section and the spring-casing and spring sectioned in part.

Like characters of reference indicate like parts throughout the several views of" the drawings.

Referring "to Figs. 1, "2 and. 3, 5 is the axle and 6 the spring-perch, to a portionof which'" above the axle one end of a radiusrod 7, is usually attached, but in my assembly I prefer to attach to the perch-bolt where it extends below the axle. A volute spring 8 is held by the perch-boltwhich passes through the inner 0011 of the spring,

axles through the agency of volute in the same plane as the rod Specification of Letters Patent.

and through a pair of washers 9 and 10, be-

.tween which washers the spring is impinged by a castellated nut 12 on the threaded end of the bolt. The adjacent faces of the washers are preferably beveled to avoid inter; ference between them and the spring within the greater but still defined limits which the washers :I'IG'lHtEIIdGCl to afford. The spring 8 is supported by an annular casing 13. which'has an inside channel 14: in which the outer coil of the spring is seated. A socket extension on one side receives an end of the radius-rod 7, to which rod the socket which is split longitudinally, is rigidly clamped by bolts 15.

here the attachment is made to the frame, as for the inner ends of the radiusrods, a bolt 6 is seated in a specially formed hanger 15, which is bolted to the frame in the manner shown in Fig. 4. Other adapta tions of the bolt-support will be made for fastening to the rear axle which is usually tubular and through which the bolt cannot pass on account of its contained mechanism, and to other support-forms, as circumstances require, and as will suggest themselves to the skilled mechanic, and without departing from the spirit of this invention.

In the operation of my device, any pressure from the radius-rod whether delivered longitudinally or laterally from the latter, but radially of the volute spring, will press the first'convolution in the line of stress toward the next convolution of the spring and into contact with it if the force is great enough, whereupon the second convolution will add its resistance. and so on cumulatively until the elasticity of all of the convolutions between the outercasing and the central bolt has been utilized. The volute suspension between the casing on the radiusrod and the central bolt afi'ords elastic resistance to stresses to or from the radiusrod in all other directions.

Having thus fully described my invention, what I claim as new and wish to secure by 'Letters'Patent of the United States, 1s

1. The combination with a radius-rod, of means having a limited elastic action in all directions by the operation of a single spring having convolutions approximately for attaching and supporting one or bothends of the rod.

2. The combination with vehicle parts, of

a radius-rod and means for connecting both ing a vollite spring having 'convolutionsin' substantially'the same pane ,as the rod which aiiord an-elastic limited movement of the rod end relative to 'thevehicleparts' v and tr-pair i of wa h rs on the 'b'ojlt'f betwee with whichthe end is connected;- 7
